All right, so this question is asking us to write out the molecular equation for a word problem that it gives us, and then also to write the net ionic equation of that same reaction.
00:11
So we will start with our molecular equation.
00:16
The problem tells us about the lithium carbonate, l -i -c -o -3, lithium -carbonate, plus our hydrobromic acid, which is aquaeus, hydrobromic acid, hbr, hbr, aquas, and this is going to be our also aquas.
00:48
Aquas.
00:49
Now, this is, as the problem describes, going to produce a precipitate, which is going to be our lithium bromide, l -i -b -r -thium bromide.
01:06
And as the name suggests, our precipitate is going to be a solid plus co2, which is a gas, co2, and gas, and liquid water, h -2.
01:28
So, nice common products, water and co2.
01:33
And our lithium bromide as the precipitate.
01:38
It's a pretty good looking reaction, and this will be our molecular reaction, our molecular equation...
